x - first number
x + 18 - second number
x + (x + 18) = 36
x + x + 18 = 36
2x + 18 = 36 | - 18
2x = 18 | : 2
x = 9
First number: x = 9
Second number: x + 18 = 9 + 18 = 27
Those numbers are 9 and 27.
Answer: Group 12
Step-by-step explanation: The element is Mercury.
Answer:
Number of 8th Graders = 360 - X
As you can see this question is not complete and lacks the essential data. But we will try to create a mathematical expression to calculate the number of students on the A honor roll which are from 8th grade.
As we know:
Total number of students on the A honor roll = 360
We are asked to calculate, number of students from 8th grade on the A honor roll.
So, let's assume that "X" represents all the students who are on the A honor roll except 8th grade.
Mathematical Expression:
Number of 8th Graders = Total number of students on the A honor roll - X
Number of 8th Graders = 360 - X
So, if you know the value of X, you can easily calculate the number of students which are from 8th grade on the A honor roll.
I am not sure if it is wrong I am sorrry.
Step-by-step explanation:
well, the arcs WS and ST together are the full half-circle and therefore 180°.
that means
5x + 37 + 3x - 9 = 180
8x + 28 = 180
8x = 152
x = 19
Answer:
d. -38
Step-by-step explanation:
Arithmetic sequence concepts:
The general rule of an arithmetic sequence is as follows:
In which d is the common diference between each term.
We can expand the general equation to find the nth term from the first, by the following equation:
In this question:
17th term:
So the correct answer is:
d. -38
